The print of the rough power balance was plain grey. It now follows the
kbp design of the print view: a title block with office logo, stand,
project, number, owner, address, work stage, date, editor and office;
header row in kbp blue, cost-group rows tinted with a lilac rule, bold
subtotals, the total including reserve as a blue band, colored
deviations in the comparison, Arial, exact print colors, and a footer
with project, stand and "Seite x von y" on every page.

In LPH 2/3 there are no circuits yet, but the office needs a power
balance by DIN 276 cost group, as in the Excel template "Leistungsbilanz -
KG400": each trade enters consumers by piece or by area (W/m²) with GLF
and cos phi; the balance sums AV and SV per cost group, adds a reserve and
derives the maximum current.
The module is separate from the circuit structure: own tables
(migration 0010), own folder src/estimate-balance and an import-free
shared calculation used by API and UI. Writes go through project commands
(estimate-balance.insert/.update/.delete with complete documents), so
revision checks and Undo/Redo apply; it is not part of project snapshots
or transfer yet. A comparison endpoint sums the device rows of all circuit
lists by cost group (longest prefix) against the estimate.
The UI adds a sidebar entry, a list of Stände (template KG 400, empty or
copy) and a spreadsheet-like editor with autosave, AMEV picker for the
GLF, totals, reserve, maximum current, comparison table and print layout.
The tests reproduce the template example exactly (143.24 kW, 148.48 kVA,
157.56 kW / 163.33 kVA with 10 % reserve, 235.75 A). See
docs/estimate-balance.md and issue #7.

The distribution-board search also matches board number and location as
soon as the boards carry them (distribution-board info card of
feature/print-view); the fields are optional in the filter, so the branch
works with and without them. Deleting a project device now asks for
confirmation like the other delete actions, since the row action is a
small trash icon.

The "Seitenansicht" link in the project header had text only, while the
other header buttons show an icon plus text.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The overview now uses the same icon buttons as the circuit list editor:
row actions are icon-only IconButtons (Pencil, Link2, Library, Trash2),
card-header and panel actions show icon plus text, and the circuit-list
link uses the new IconLink. The version history uses Undo2/Redo2, a
chevron toggle and a RotateCcw restore action. Page-header buttons stay
Bootstrap buttons with a lucide icon so the upcoming "Seitenansicht"
button of feature/print-view merges without conflicts and matches them.
The Verteilungen and Projektgeräte cards get a PM-style filter bar:
search plus MultiSelectDropdown (checkbox list with "Alle", closes on
outside click and Escape) and "Zurücksetzen" while a filter is active.
Only the bar collapses; the state is kept per card in localStorage and a
collapsed active filter shows "Filter aktiv". The header row shows
"x von y", and an empty-state row explains when filters hide everything.
The filter logic is a pure module (overview-filters.ts) with node tests;
selections that are no longer offered (deleted floor) are ignored.
IconButton now imports React explicitly like the other components that
are rendered in node tests with the classic JSX runtime.

AppShell showed the sidebar only on the project list and overview, so it
disappeared on the building structure page and in the circuit list
editor. It is collapsible, so it now stays on every page. Only the print
view, a stand-alone document opened in its own tab and printed as PDF,
keeps the full width.

Removing the shadow-sm classes touched the page markup of the project
overview, which other branches change as well. The card rule now sets
Bootstrap's --bs-box-shadow-sm to the card shadow instead, so cards with
and without shadow-sm look the same and the pages stay as they are on main.

Projects with several buildings could not be structured: floors and rooms
hung directly off the project. Floors can now belong to a building
(migration 0009: table buildings, nullable floors.building_id). Rooms and
distribution boards keep their floor; their building follows from it.
Existing floors stay without a building.
Buildings use the location-structure command store with
project-building.insert/.update/.delete, inverses and persistent Undo/Redo;
deleting a building with assigned floors is rejected. Floor commands carry
buildingId since command version 2. Version 1 floor commands from existing
history predate buildings and are upgraded with buildingId = null before
they are executed and persisted, so forward and inverse keep one version.
Project snapshot schema 7 stores buildings and floor.buildingId; versions
1-6 are upgraded without buildings. Restore and portable transfer include
buildings, and the transfer remaps building ids.
Buildings, floors and rooms move from the project overview to their own
page /projects/:id/struktur with three columns (Gebäude -> Etagen -> Räume)
that filter each other, and a sidebar entry. Floor selects in the board and
room dialogs are grouped by building. Unchanged dialogs close without a
command. Details in docs/building-structure.md; see issue #6.

Cards had a 3px petrol bar on the top edge, and Bootstrap's shadow-sm
class overrode their own shadow with !important. They now use the PM app
surface: a 1px border all around, a 16px radius and a soft diffuse shadow
with a faint inner highlight, with a stronger shadow and a weaker highlight
in dark mode. The shadow-sm classes are removed from the cards so the
shared rule applies. Menus, drawers and dialogs keep their shadows.

crypto.randomUUID() is only defined in secure contexts (HTTPS or
localhost). Opened over plain HTTP from another machine in the LAN, the
circuit list editor failed with "crypto.randomUUID is not a function"
whenever it created a circuit, device row, circuit group or distribution
board component, including typing into the -frei- row.
createClientId() uses crypto.randomUUID() where available and otherwise
builds an RFC 4122 version 4 UUID from crypto.getRandomValues(), which
works in every context. AGENTS.md notes the rule.

The selected GZF cell shows a small table-icon button, and Alt+ArrowDown opens
the same picker from the selected or edited cell; Escape closes it. The
shared GzfPickerModal is reused. The picked mean value is committed through
commitEdit with an explicit target cell, so it is a regular undoable edit on
device rows, compact circuits, reserve circuits and the -frei- row.

Per-circuit cross-section recommendation as a separate module attached to
the circuit list. It never writes project data itself: "Übernehmen" applies
cable type, cross-section and length through the regular circuit.update
command, so revisions and Undo/Redo stay intact.
- Pure domain module (src/cable-sizing) with IEC 60364-5-52:2009 Annex B
tables for PVC and XLPE, copper and aluminium, methods A1, A2, B1, B2, C,
D1, D2 and E. Every value was cross-checked against public reproductions;
where sources differ the lower value is used (docs/cable-sizing-module.md).
- Temperature and grouping between table values round to the safer value;
values outside the tables return no result instead of a factor of 1.
Ground methods use B.52.18 (D2) and B.52.19 A (D1).
- Overload protection: circuit-breakers In <= Iz; gG fuses additionally
I2 <= 1.45 Iz with I2 = 1.6/1.9/2.1 In.
- Inputs prefilled from the circuit: power, phase (group or device rows),
project voltage, power-weighted cos phi, length and protective device.
- Opened from a "Leitungsberechnung" button in the row actions, not from a
grid cell, so cable cells keep the spreadsheet behavior.
- Stateless API under /api/cable-sizing; no database table or migration.

- Project settings gain siteAddress, workStage, projectLead and
projectEditor (project.update-settings schema version 3, migration 0009);
versions 2 and 1 stay executable and keep the current cover values.
Snapshot schema 6 carries the fields; older versions upgrade with null.
- Global office profile (office name/address) next to the document logo:
table document_branding_settings, PUT /api/document-branding/office,
editable from the print view toolbar.
- Cover page reads all fields; empty values show the "[ergänzen]" marker.
The Planstände editor column shows the project editor.
- Shared logo constants moved to a dependency-free module so the Next.js
bundler can import them.

- Seitenansicht (/projects/:projectId/print): tabular cover page, board
overview with supply structure and power sums, one plan per board with a
repeating title block; PDF via the browser print dialog with named @page
rules (A4 portrait cover, A4/A3 landscape plans, page x of y).
- Distribution-board info card (board number, location, fed-from, remark)
in the board edit dialog, persisted through the additively extended
distribution-board.update command (migration 0008, snapshot schema 6,
legacy subtree commands normalized).
- Global document logo upload (PNG/JPEG/SVG, max 2 MB) outside project
revisions and snapshots.
- fed-from stays free text; the overview hierarchy and cumulated sums are
preliminary until the feed link is modeled.

- Replace the "Filtern" text buttons with a funnel icon next to the column
label; an active filter is highlighted and shows its value count.
- Header labels no longer break inside words (e.g. "Bemerkung"); hyphens
are non-breaking and a trailing unit moves to its own line, so all
headers share one height.

- New IconButton/IconButtonSeparator component based on lucide-react.
- Toolbar: icon plus text, grouped into history, view and insert blocks.
- Group headers: compact icons for add circuit, upstream fuse (VS), group
RCD (FI), edit, move up/down, renumber and delete; the header no longer
overflows the grid.
- Rows: add device, delete circuit (trash) and delete device (ListX).
- The previous German labels remain accessible names and tooltips;
destructive actions highlight in the danger color.

Running the stack on built output stopped the idle CPU load, but the
remaining findings from the deployment report were still open.
The Dockerfile is now multi-stage. The prod target runs on node:24-slim as
the "node" user instead of root and carries only its runtime dependencies;
"npm prune --omit=dev" drops tsx, drizzle-kit and typescript. The migration
scripts need drizzle-orm and better-sqlite3, both regular dependencies, so
they keep working. The dev target keeps devDependencies for compose.dev.yaml.
Both compose files get a mem_limit. The server stack also sets memswap_limit
to the same value, so a leak lets the OOM killer replace the container
instead of pushing the host into swap. The Express API is no longer
published on the host: it has no authentication and is reached through the
Next.js rewrite. Development ports are bound to the loopback interface.
Services drop all capabilities and run with no-new-privileges.
SIGTERM and SIGINT now close the HTTP server and the SQLite handle and exit,
instead of only logging the signal and waiting for the container's SIGKILL
ten seconds later. server.closeIdleConnections() releases the keep-alive
sockets the Next.js server holds, which would otherwise keep server.close()
pending for the whole grace period. The compose start commands exec into
node, because otherwise sh stays the foreground process and the signal never
reaches it.
Delete scripts/docker-start.sh rather than fixing its unsupervised
background API: both compose stacks set their own command, so the
single-container entrypoint has no caller left. Also remove drizzle.config.js
(a stray tsc artifact drizzle-kit never reads) and the pre-Next index.html
and styles.css.

compose.yaml overrode the image's own entrypoint to start "tsx watch" and
"next dev" with CHOKIDAR_USEPOLLING and WATCHPACK_POLLING enabled. The
built dist/ and .next from the image were never used, and the polling
watchers kept both containers busy around the clock whether or not
anyone used the application.
Split the two use cases: compose.yaml now runs node dist/server/index.js
and next start with no source mounts and no watchers, and the watching
setup moves to compose.dev.yaml.
next build writes the rewrite destinations from next.config.mjs into
.next/routes-manifest.json, so next start cannot pick up API_INTERNAL_URL
at runtime the way next dev does. Pass it as a build argument.
Give the web container its own probe. The healthcheck hit "/", which
redirects to "/projects", and fetch follows redirects, so every probe
rendered two pages every five seconds. "/health" could not serve as the
probe because next.config.mjs rewrites it to the API. Add "/web-health"
as a route handler, exclude it from the proxy matcher, and relax both
intervals to 30s.

Synchronizing a project device pushes its quantity onto every linked
device row, but manualQuantity is not part of the sync snapshot and was
left untouched. A device whose quantity is lower than the row's left the
row at manualQuantity > quantity, violating the snapshot invariant.
The violation surfaced far from its cause: the invariant is only checked
when a full state snapshot is read, and the automatic snapshot runs every
25 revisions. A project could therefore accumulate the broken row
silently and then reject every subsequent command, because the failing
validation rolls back the whole transaction including the revision bump.
Recompute manualQuantity as the synchronized quantity minus the total of
the linked external objects, matching the invariant that
assertCircuitDeviceRowQuantity enforces elsewhere, and reject a
synchronized quantity that falls below that total.

Node 22 leaves active LTS at the end of October. Move the Docker base
image and the documented local requirement to Node 24.
Pull @types/node from ^25 down to ^24 so the type definitions no longer
describe a newer runtime than the one in use. Types ahead of the runtime
let TypeScript accept APIs that are not there at execution time; the
opposite direction is harmless.
Add an engines field to record the supported version. No .nvmrc, since
the project is not used with a Node version manager.

Adds a persistent dark/light theme toggle (localStorage +
data-bs-theme on <html>) so it applies globally, including the
circuit editor route which has no visible sidebar. An inline
beforeInteractive script sets the theme before hydration to avoid a
flash of the wrong theme.
Bootstrap components pick up data-bs-theme automatically; the custom
circuit-grid CSS previously used ~150 hardcoded hex colors, all
converted to semantic tokens in globals.css with light/dark values.
Verified with a headless-browser pass across the project list, project
detail page, circuit editor, project-device drawer and a settings
modal in both themes; no console errors.

- circuit-list-editor-api.md: next-identifier moved under
/projects/:projectId and now documents its 404 scoping behavior.
- current-architecture.md: clarify that the BMK trigger register's
DB-level normalization is ASCII-only and describe the added
application-level Unicode-aware uniqueness check that closes the
umlaut gap; note the additive migration 0006 indexes.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Full-codebase review turned up five real correctness/security bugs and
a dozen smaller inconsistencies; all are fixed here with matching test
coverage:
- BMK uniqueness silently allowed German-umlaut duplicates ("Ä1" vs
"ä1") because the DB's normalized index only folds ASCII case. Added
a shared Unicode-aware pre-check used by every circuit/component
insert and rename path (one of which had no pre-check at all).
- CircuitDeviceRow.simultaneityFactor had no upper bound at the row
level (command model and snapshot/restore schema), unlike every
sibling entity, letting a bad value silently corrupt power totals.
- Grid cell editing silently misread German thousands-separator input
("1.500" parsed as 1.5); "." is now rejected outright with a clear
message instead of guessing.
- The editor's shared command runner (runCommand/applyHistory) had no
re-entrancy guard, so a double click/drop could fire the same
command twice and race a BMK collision or revision conflict. Added a
synchronous ref guard plus isSaving on the buttons that lacked it.
- GET .../next-identifier leaked circuit-numbering state for sections
in other projects (no ownership check, 400 instead of 404). Moved
under /projects/:projectId and scoped it.
Also: added the missing circuits.section_id / circuit_device_rows.
circuit_id indexes (migration 0006), gave FormModal a focus trap /
Escape-to-close / focus restore and rebuilt ProjectSettingsModal on
top of it instead of duplicated markup, removed dead code (3 orphaned
domain model files, an unused persistence helper, a wrapper only used
by its own test), pointed the project page at GET /projects/:id
instead of listing+filtering client-side, closed the gap between the
documented 18 MB CSV limit and the ~17.17 MiB actually enforced, added
missing upper bounds on several free-text fields, filled in nine
missing German labels in the revision timeline, replaced a
key-order-fragile JSON.stringify equality check with a real field
comparison, made an implicit sort-order assumption in three
renumbering helpers explicit, cleared the sidebar's target selection
when it no longer resolves after a tree reload, and fixed
updateGlobalDevice to check-then-write instead of write-then-check.

Review of the logging work from the previous commit turned up a real
correctness issue: the uncaughtException/unhandledRejection handlers
logged the error but let the process keep running, which silently
disabled Node's default crash-on-fatal-error behavior and could leave
a zombie process serving broken requests instead of restarting. Both
processes now log and then exit(1); restart: unless-stopped is added
to both services so Docker actually brings them back up.
Also: harden the logger against JSON.stringify throwing on
non-serializable meta, log aborted (closed-before-finished) requests
in the API access log, and stop the Next.js proxy from logging the
Docker healthcheck's request to "/" every few seconds so real
navigation events aren't drowned out.

Adds a leveled JSON logger (error/warn/info/verbose/debug, controlled via
LOG_LEVEL) wired into the Express API (access log, error middleware,
crash handlers, memory heartbeat) and the Next.js server (page-request
proxy, instrumentation crash handlers, heartbeat). LOG_LEVEL is exposed
through compose.yaml, and both services now rotate their Docker logs
(json-file, 20m x 10 files) instead of growing unbounded. Intended to
capture long-running diagnostic data for the intermittent 502s seen on
the Docker host.
